Job Summary
Citizens and permanent residents only - we do not sponsor and cannot hire non-citizens or PRs. We work 6 days a week in the office in downtown San Francisco with one Saturday off per month no remote available.
Aurelius Systems is a directed energy company developing edge-deployed laser systems for counter-unmanned aerial systems (cUAS)we shoot down drones with laser an era where threats are increasingly small numerous and easily manufactured our mission is to provide scalable advanced and cost-effective defense solutions for the US and our allies. Were building our team to launch our flagship product: the Archimedes laser sentinel. Join us in delivering cutting-edge technologies to protect our servicemen servicewomen and domestic security forces.
Role Overview:
We are seeking an inventive Power Electronics Engineer to drive the design development and validation of robust battery and high-voltage power systems for rugged edge-deployed laser defense systems. You will lead battery management systems diode driving electronics high-voltage wire harnesses and field-ready prototype validation. This role spans conceptualization through production emphasizing a strong bias toward hands-on testing and iterative electronics prototyping in demanding defense environments.
Key Duties and Responsibilities
- Battery Pack & Management Systems:
- Develop and validate battery packs and management electronics ensuring effective thermal and power management
- Conduct thermal and electrical performance analyses and testing for rugged battery systems.
- Architect battery systems for rapid power delivery.
- High Voltage Converter and Driver Electronics:
- Design high-voltage DC/DC converters rectifiers inverters diode drivers power distribution units and related control circuits
- Perform electrical simulations (SPICE MATLAB/Simulink) to optimize performance efficiency and reliability.
- Wire Harness Design & Fabrication:
- Create ruggedized wiring harnesses suitable for high-power laser diodes and motors
- Select and specify connectors cables and components adhering to electrical environmental and mechanical standards.
- Prototype Development & Testing:
- Drive hands-on prototyping assembly and rigorous field testing of power electronic systems
- Execute electrical environmental vibration shock and robustness tests to validate system reliability.
- Design for Manufacturability (DFM):
- Conduct DFM reviews to optimize electronics designs for efficient reliable and cost-effective production
- Collaborate closely with suppliers and fabricators to ensure manufacturability and quality standards.
- System Integration & Cross-functional Collaboration:
- Partner with mechanical optical and robotics teams to integrate electronics into laser platforms
- Provide technical guidance during system assembly integration and field deployment.
- Documentation & Compliance:
- Generate detailed schematics BOMs wiring diagrams and assembly instructions.
- Ensure compliance with relevant safety standards MIL-STD and ITAR requirements.
Qualifications
- 3-8 years in power electronics or electrical engineering roles (defense aerospace robotics).
- Proficient in electrical design tools (SPICE MATLAB/Simulink Altium Designer).
- Strong background in battery management high-voltage electronics and diode driving circuits.
- Hands-on experience with wire harness design and rugged electronic system assembly and integration.
- Familiarity with thermal management EMI/EMC considerations and defense-grade specifications.
Education:
- BS/MS in Electrical Engineering Power Electronics or a related field.
Soft Skills:
- Extreme bias for action rigorous testing mindset and strong problem-solving abilities.
- Excellent communication collaboration and adaptability in a fast-paced development environment.
Nice-to-Haves:
- Experience with long-duration system deployment in harsh environments.
- Familiarity with MIL-STD standards and ITAR compliance.
- Background in EMI/EMC design and shielding.
- Security clearance or ability to obtain one.
Why Join Aurelius Systems
- Drive innovation in cutting-edge directed energy defense technology.
- Contribute directly to national security with robust and scalable hardware solutions.
- Build more in 12 months than most engineers do in 5 yearswe field test monthly on our own 400 acre range executing against a $151B MDA SHIELD IDIQ contract.
- Grow fast: engineers here typically get promoted 1-2x per year. Erick Brito went from Founding Robotics Engineer to Lead in 12 months.
- Work alongside a founding team from to build what directed energy should have been.
We work 6 days (yes well relocate you) a week because thats what it takes to ship real hardware to real operators. If you want balance we respect that. If you want to buildkeep reading.
